“…This is because the arrival rates of the flows can be low fractions of the indivisible R TS (defined as the guaranteed Reprinted from ref.

This case is most likely to happen in sensor networks since their arrival rates may be particularly low.…”

WSANs provide the infrastructure for many applications of CPS. Lots of these applications use the IEEE 802.15.4 standard. However, it does not provide any means of differentiated services to improve QoS for time-critical and delay-sensitive events. A large amount of efforts have been made to address such issues. In this chapter, an overview on some interesting mechanisms used in existing adaptive and real-time protocols in compliance with IEEE 802.15.4 is presented. Careful examination of these research works reveals that by optimizing the original specifications and dynamically adjusting the protocol parameters, the total network efficiency can be significantly improved. Nevertheless, there are still certain challenges to overcome in pursuing the most appropriate protocol without introducing unacceptable side-effects. These standards have greatly encouraged to bridge the real-time physical world's applications/objects to cyber world for diverse range of time-critical applications. The communication and computing capabilities of cyber core are utilized to control/monitor real world's objects/applications. KeywordsThe performance of CPS depends upon QoS of the underlying network. In practice, applications' requirements vary in different environments. For example, in case of environmental surveillance, alarm packet should be prioritized as compared to normal data readings. In WBANs, life critical physiological readings should be delivered on time to the health services provider. However, IEEE 802.15.4 does not have such

“…Currently, the IEEE 802.15.4 [8] model is implemented in detail. Among others, both ZigBee and, to some extent, WirelessHART devices rely on the physical layer and data link layer specified in this standard [9], which makes it especially relevant for the CPS community. Contention-based (Carrier-Sense Multiple Access with Collision Avoidance) as well as contention-free (Guaranteed Time Slot, GTS) access mechanisms are implemented, as descibed in the standard.…”

Abstract-Cyber-Physical Systems (CPS), such as networked control systems, are increasingly deployed over wireless networks. Given the sensitivity of control systems to networking conditions such as packet drops, delays and jitters, it is important to verify and evaluate the control system properties under realistic wireless networking deployment scenarios. However, current research is often based on simplistic models of the wireless network physical layer behaviors. In this paper, we point out deficiencies in the existing simulation methods for the performance evaluation of wireless networked control systems and present a novel simulation framework for wireless network control systems. Our approach aims at capturing the effects in the physical layer more accurately than state-of-art simulators are capable of. An integrated simulation tool, based on open-source solutions, is presented and a case study of a networked control system is also provided to illustrate the capabilities of our simulation tool.

Summary The vision to connect everyday physical objects to the Internet promises to create the Internet of Things (IoT), which is expected to integrate the diverse technologies such as sensors, actuators, radio frequency identification, communication technologies, and Internet protocols. Thus, IoT promises to transfer traditional industry to advance digital industry known as the Industry 4.0. At the core of the Industry 4.0 are the wireless sensor networks (WSNs) and wireless sensor and actuator networks (WSANs) that led to the development of industrial wireless sensor networks (IWSNs) and industrial wireless sensor and actuator networks (IWSANs). These networks play a central role of connecting machines, parts, products, and humans and create a diverse set of new applications to support intelligent and autonomous decision making. The IWSAN is a promising technology for numerous industrial applications because of their several potential benefits such as simple deployment, low cost, less complexity, and mobility support. However, despite such benefits, they impose several unique challenges at different layers of the protocol stack when deploying them for various monitoring and control applications in the Industry 4.0. In this article, we explore IWSAN, its applications, requirements, challenges, and solutions in the context of industrial control applications. Our main focus is on the medium access control (MAC) layer that can be exploited to satisfy such requirements. Our discussion presents extensive background study of the MAC schemes and it reviews the MAC protocols of the existing wireless standards and technologies. A number of application‐specific MAC protocols developed to support industrial applications, which are not part of these standards, are also elaborated. We rationalize to what extent the existing standards and protocols help in solving such requirements as laid down by the Industry 4.0. In the end, we emphasize on existing challenges and present important future directions.
